Erica Synths - Black VCA

Erica's Black VCA is a very nice HiFi-VCA for audio signals, able to handle and to attenuate control voltages with very high amplitudes and with it's 2nd CV input featuring a smooth fading between linear and logarithmic characteristic.

The VCA's input level is set with the gain control and the initial bias is adjustable with the large potentiometer which you put in 12h-position for standard applications with posivie going CVs.

The two CV inputs accept sontrol voltages with amplitudes up to 10Vpp and they have scaling potentiometers which can attenuate the signal from -80dB to 0dB (unity gain with a CV with 10V amplitude).
CV1 has a linear characteristic, the second CV input's characteristic depends on the response potentiometer which allows for fading from linear to logarithmic.
